django-autocomplete-light’s purpose is to enable autocompletes quickly and
properly in a django project: it is the fruit of half a decade of R&D and
thousands of contributions. It was designed for Django so that every part
overridable or reusable independently. It is stable, tested, documented and
fully supported: it tries to be a good neighbour in Django ecosystem.

Any change is documented in the Change log for django-autocomplete-light, so upgrading from a version
to another is always documented there. Usualy, upgrade from pip with a command
like pipinstall-Udjango-autocomplete-light. Check the CHANGELOG for BC
(Backward Compatibility) breaks. There should is no backward compatibility for
minor version upgrades ie. from 1.1.3 to 1.1.22, but there might be some
minor BC breaks for middle upgrades ie. 1.2.0 to 1.3.0.
